------------------------------------
Summary: Stats autogather calculates the min statistic incorrectly
Key: HIVE-29275
URL: https://issues.apache.org/jira/browse/HIVE-29275
Project: Hive
Issue Type: Bug
Reporter: Thomas Rebele
In stats_histogram.q autogather gets enabled and then rows are inserted into a
newly created table. The minimum value for column e is
[-123.2|https://github.com/apache/hive/blob/55d9ab7d6b00fa510be791b9de55974f61c90519/ql/src/test/queries/clientpositive/stats_histogram.q#L20].
However, {{DESCRIBE FORMATTED test_stats e}} shows
[-10.2|https://github.com/apache/hive/blob/55d9ab7d6b00fa510be791b9de55974f61c90519/ql/src/test/results/clientpositive/llap/stats_histogram.q.out#L364]
as the minimum value.
When executing {{ANALYZE TABLE test_stats COMPUTE STATISTICS FOR COLUMNS;}}
before the {{DESCRIBE FORMATTED test_stats e}} command, the min value is -123.2
as expected.
